Plant Pathology Graduate Program Requirements

Plant Pathology offers two masters degrees; the non-thesis master of plant pathology (MPP) and the thesis master of science (MS), and the doctor of philosophy (Ph.D.) degree.

Master of Science (M.S.) Degree Requirements

The Master of Science (M.S.) degree requires students to complete a minimum of 30 semester (credit) hours and an original master’s research thesis. The Graduate School does not give credit for non-credit course work (i.e. non-departmental seminars, workshops, short courses, conferences, and any “life experience” offerings). Furthermore, the Graduate School does not allow credit by examination.

The student must have an advisory committee composed of the Chair of the committee (major advisor) and two additional members of the graduate faculty. The Committee must be formed and the Plan of Work (PoW) submitted before the start of the student’s 3rd semester.

To fulfill the minimum 30-semester hour’s requirement, students must successfully complete:

  • A minimum of 18 semester hours of letter-graded courses (A, B, C). These must be NC State University or inter-institutional courses. A maximum of 12 semester hours may come from the NCSU Post-Baccalaureate Studies (PBS). The graduate level courses must be “B” grade or better;
  • and have final GPA of at least 3.0
  • of which 12 semester hours are the required Plant Pathology core curriculum courses;
  • presentation of the thesis research update in the third semester at the MS/PhD Symposium normally in fall semester (M.S. students register for PP601);
  • Supervised teaching for the M.S. is optional (PP685).
  • Minimum of six (6) semester hours of graduate-level courses beyond the core;
  • Remaining hours in plant pathology or related field of study with no more than six (6) semester hours of 400-level (undergraduate) courses that cannot be in plant pathology;
  • Master’s Thesis Research (PP695) semester hours unlimited as long as the program minimum requirements are met;
  • The grade for all Satisfactory (S)/Unsatisfactory(S) graded courses must be “S”;
  • Credit hours for the following courses may NOT be used to satisfy the 30-credit hour requirement: Non-Thesis Master’s Examination (XXX 690), Summer Thesis Research (XXX 696), Non-Thesis Master’s Continuous Registration (XXX 688 and XXX 689). If taken, these cannot be included in the PoW.
